Superabsorbent crystal polymer (can be purchased online)
How is it Working?:
Soak the crystals in water and see how fast they absorb water! In just a few minutes you’ll have a huge bowl of icy looking crystals, only they’re not cold! Dry them out on a paper towel, and you can use them again!
What Does It Teach?:
Discover how polymers perform very important functions in everyday life. Sometimes referred to as Hydrogel, they’re used in everything from baby diapers to environmental cleanup materials! Aside from their environmental and industrial uses, superabsorbent crystals are a great way to teach kids about color and light!
